Multicooker shows E13 and aborts the program; may be accompanied by unusual noises from the valve.

Safety first: Ensure the cooker is fully depressurized before touching the steam release valve. Steam can cause serious burns.

Steps to resolve:

• Remove the valve: Detach the steam release valve from the lid according to the Siemens manual (usually by pulling straight up or twisting).
• Disassemble and clean: If the design allows, separate the cap, spring, and internal plug. Clean all parts with warm soapy water, removing any starch or scale. Rinse and dry completely.
• Inspect seals and spring: Check the silicone or rubber seal for cracks or flattening. Ensure the spring is not rusted or deformed. Replace the valve assembly if any parts are compromised.
• Reassemble correctly: Follow the Siemens diagram to reassemble the valve in the correct order and orientation. An incorrect assembly can trigger E13.
• Test with water: Run a short pressure cycle with water only to verify that the valve opens and closes smoothly without error.

When to call a technician: If the valve appears fine but E13 persists, the pressure control circuitry or sensor may be faulty and requires professional diagnosis.
